Corporate Sustainability: Tips for your sustainable startup

Founding a company is a far-reaching process that involves many decisions. Are you working hard to make your company viable, but want to take the environment and society into consideration? Even if your business model is not directly related to environmental protection or sustainability, you can build your startup as a responsible, socially and environment-friendly company where fast growth, scaling the business model and maximum profit are not the top priority. This type of business model is called a zebra startup - the opposite of a unicorn startup. Emphasis on the common good benefits both the entrepreneur and the environment and society. Sustainable commitment boosts the corporate image, ensures stronger brand loyalty among your customers, brings all kinds of cost savings and makes your startup more competitive in the long-term.

The following practical tips and suggestions will help you make sustainability an integral part of your company from the outset and thus fulfill your corporate and social responsibility:

Sustainable HR management means that your startup treats its employees equally, promotes their health and satisfaction and acts in an environmentally conscious manner at the same time: This will ensure that your workforce remains motivated, healthy and environmentally conscious in the long term.

• Fair pay and working conditions: Ensure that all employees are paid fairly and have safe, healthy workplaces.

• Training and development: Offer training, further education and career planning to boost you’re your employees’ skills.

• Flexible working hours and remote working: Create opportunities for flexible working hours or remote working to improve the work-life balance.

• Health promotion: Offer schemes to promote physical and mental health, such as sports activities or stress management workshops.

• Environmentally conscious action: Organize measures such as paperless working, sustainable office materials or environment-friendly transport.

• Participation and co-determination: Involve employees in decisions to increase their satisfaction and identification with the company.

2. Sustainable purchasing and operation: conscious use of resources

The responsible use of environment-friendly materials, product parts and other resources forms the foundation of your sustainability-oriented startup.

• Supplier selection: Work with local suppliers to cut transport routes and emissions. Make sure that they operate sustainably, follow environment-friendly manufacturing procedures and offer appropriate delivery options.

• Materials & devices: Use environment-friendly and recyclable materials. Paper or compostable packaging is often better than plastic. Pay attention to environment-friendly manufacturing processes, such as the circular economy and avoiding emissions. Certifications such as the Blue Angel or FSC can offer guidance.

• Fair production: Choose sources that guarantee fair working conditions and environment-friendly production. Avoid suppliers who do not provide information about the working conditions in their manufacturing plants or even use environmentally harmful materials.

• Circular economy: Use more products that can be reused or recycled instead of buying disposable items. Invest in reusable packaging or reusable systems.

• Minimize paper consumption: Use digital alternatives and print only when necessary. If paper is necessary, use recycled paper.

3. Environment-friendly marketing: do good and talk about it!

You can design your marketing strategies to be environment-friendly, socially responsible and sustainable in the long term. The focus is on promoting your products and services in an environment-friendly manner that also promotes fair working conditions and long-term effectiveness.

• Digital advertising: Avoid printed advertising materials and use online marketing and social media instead. Email campaigns and SEO optimisation generate your reach. When using digital advertising displays, ensure that people and animals are not disturbed by the light.

• Green branding: Focus on sustainable messages and explain to your customers transparently why and how your company is environmentally responsible. Sustainability can make you stand out from the competition. Background information about your company can be used for informative content on social media, company blogs and newsletters.

• Collaborations: Work exclusively with sustainability-oriented influencers and companies to increase your reach. Collaborations with sustainable partners can open up new markets for you.

• Resource-saving events: Use and organise online webinars instead of physical events to minimise resource consumption. If events in real places are necessary, opt for climate-neutral venues and sustainable catering.

4. Environment-friendly logistics: sustainable distribution pays off

Establish measures and processes aimed at minimising the environmental impact of goods movement and sales.

• Shipping: Choose climate-neutral shipping options, e.g., with CO2 compensation or plastic-free packaging. Work with logistics companies that focus on sustainable supply chains. Use low emission means of transport, for example, transport in the same city could be environment-friendly by using cargo bikes.

• Warehouse: Use motion detectors to light the warehouse and reduce energy consumption. If you have free storage capacity, you can team up with other companies or conversely, use their storage space instead of renting it yourself.

• Sustainable partners: Work with socially and environment-friendly business partners. Joint initiatives for social interaction and the environment can increase your impact and enhance your image.

Hamburg-based impact startups creating a good climate

Some Hamburg-based startups focus on making purchasing, packaging and deliveries more sustainable:

The toern company reduces the shipping routes for returns. If an item is not to your liking for whatever reason, toern’s online interface sends it to the nearest customer’s address instead of back to the supplier which saves transport costs. The traceless startup near Hamburg produces a biodegradable organic plastic granulate from leftover grain, which can be used for environment-friendly packaging film and shipping bags.

The Hamburg-based startup Wildplastic ensures that plastic does not end up as non-biodegradable waste in the environment. The waste is processed into plastic bags and packaging and returned to existing recycling cycles.

Boomerang develops reusable shipping packaging

We took a look behind the scenes of exciting startups and present Boomerang: With reusable shipping packaging for online retail, Boomerang replaces disposable shipping packaging used by online shops to send goods to end consumers. The system is based on an intelligent deposit model and a return logistics system that allows the packaging to be reused up to 50 times.

Holy Technologies furthers decarbonisation

Holy Technologies develops recyclable carbon fiber solutions for high-performance applications in Energy, Automotive and Aerospace. The goal is to develop significant technology advancements, that ultimately enable the decarbonisation of the manufacturing sector.

Organise your own and your employees' mobility consistently with environment-friendly transport systems and means of transport. You will find a variety of suitable offers, especially in cities.

• Business trips: Reduce business trips and rely more on video conferencing to cut travel costs and CO2 emissions. If possible, take the train for business trips and avoid the car or plane. A mix of train travel and car sharing at your destination is also possible.

• Employee mobility: Offer your employees incentives for cycling or rail travel, e.g., by subsidising job tickets or company bikes.

• Car sharing: Enable your employees to use sustainable car sharing services and reduce or eliminate their own expensive and time-consuming vehicle fleet. Local providers such as cambio offer special conditions to companies such as guaranteed constant vehicle availability at set times.

6. Saving resources in the office: use reused and refurbished

There are many ways to use materials, energy and water consciously and avoid waste in everyday office life.

• Office furniture: You don't have to buy everything new. Check well-known online portals to see whether you can buy office furniture second-hand.

• Avoid waste: Implement a zero-waste concept with clear recycling guidelines. Separate waste consistently and reduce unnecessary paper consumption.

• Technology: It also makes sense to purchase refurbished IT devices - i.e. used computers and smartphones that have been refurbished by a manufacturer or retailer and can be used for longer.

• Office supplies: Use environment-friendly office supplies such as recycled paper, refillable pens and ecological cleaning products. For toilet paper, your Hamburg startup has an exemplary sustainable supplier right on its doorstep: the non-profit Hamburg-based company, Goldeimer, sells recycled toilet paper, among others, and your purchase supports education, awareness and projects for access to water, sanitation and hygiene worldwide.

• Plants in the office improve the indoor climate, increase well-being and absorb pollutants - you can also buy plants second-hand.

• Save energy: Opt for energy-efficient devices, LED lighting, green website hosting and use electricity from renewable sources. If you want to operate your own company building in a CO2-neutral manner, you can get advice on photovoltaics, electricity storage, heat pumps and more from the successful Hamburg startup 1KOMMA5°.

7. Responsible company parties and team events: less is more

Sustainably organised company parties and events show appreciation for the environment and society, enhance the positive image of your startup and can save costs. They also foster a sense of positivity among participants by demonstrating that your startup is taking responsibility.

• Catering: Choose regional, seasonal and vegan options to reduce CO2 emissions. If you have leftover food, you can donate it to organisations such as foodsharing or the Hamburger Tafel.

• Venue: Choose sustainable event locations with an environment-friendly energy supply.

• Giveaways: Use sustainable gifts such as reusable drinking bottles or seed bombs instead of useless plastic gadgets.

• Entertainment: Instead of a harbor tour or bowling alley, you can organize a playful clean-up near your company headquarters as a team-building activity.

• Waste avoidance: Plan events in such a way that as little waste as possible is produced, e.g. by using reusable crockery.

Your startup can do immediate good and improve the company's image by making donations and demonstrating social commitment at the same time. Taking on social responsibility strengthens trust among customers, partners and employees.

• Corporate Social Responsibility (CSR): Get involved in social and ecological projects, e.g., through partnerships with suitable local initiatives.

• Fundraising campaigns: Use a portion of your sales for sustainable and social causes or support local projects.

• Volunteering: Encourage employees to get involved in social initiatives and support fundraising campaigns. Offer at least one fixed day off a year for this. The Hamburger Freiwilligenagenturen has on overview of organisations in Hamburg currently in need of support.
