        At Spark Sustainability, we’re on a quest to spark collective action on climate change, and we thought we’d kick off 2019 by explaining why that’s such a big deal.


        Have you ever been in a building where the fire alarm went off and nobody moved or looked worried? This actually happened just before Christmas at the shared office where Spark works, and it makes you think about what it is that makes people act. It’s not the fire alarm. It’s not even the smoke: it’s when we see other people rushing to get out or calling for help (B. Latane & J.M. Darley,1968). The same principle applies to stopping climate change: as long as nobody really does anything; nobody else really does anything either.

        Understanding the fire alarm situation is the key to understanding how to stop climate change: since humans use social cues to recognize emergencies, the very physical, economic and political problem of climate change is at the same time a social problem that we can approach by changing social norms.


        Now, let’s backtrack for a second; what is it that actually needs to be done in order to stop climate change?

        Since more than 75% of the world’s emissions come from the energy sector, we first and foremost must change the way we produce energy. We can do this for example by installing more solar and wind power and more geothermal heat pumps, as well as by electrifying much of transport and heat production (because electricity is easier to produce with zero emissions than heat or fuel for transport is). However, energy production is only half the problem with energy – the other part is how, when and where the energy is used. To solve this, we need to get accustomed to using energy when it is available, instead of as now just using it whenever we feel like it. This can be done with the help of technology, but it does require people to be eager to use that new technology. (CAIT, 2018; IPCC, 2014; IEA 2017; Pöyry 2018)


        The second and third steps to take in order to stop climate change are to look over the way we feed the world’s population and how we produce things like steel and cement, which are currently made with extremely carbon-intensive processes. (IPCC, 2018)


        All three of these changes (energy, food and process industries) are large structural, technical and economical challenges. This makes for confusion when paired with the conclusion of the IPCC SR15 report (the one published last October) that citizen climate action is going to be part of the solution to climate change. How do our personal actions matter if the solution requires big political decisions and large investments to be made? This is where the magic happens:


        1. Personal climate actions add up to large emission savings when many are acting (van Vuuren et. al., 2018)
        2. They also send a strong message to businesses that cleaner goods and services are in demand

        BUT, both of these things are actually just the icing on the cake.

        The real reason to promote personal climate action is because people taking action in their own lives is actually one of the best ways to get to a society that implements the policy-level change that is truly needed.


        That’s right: Research on social behaviour suggests lifestyle change can build momentum for systemic change. This is because others notice your everyday actions, and eventually new social norms are formed. In addition, widespread climate action, such as eating less meat or driving less, can give an extra push in areas where existing policies aren’t enough to reach our emission targets.


        The social ecological model on how personal action influences society, culture and norms (e.g. I. Gaziulusoy, 2012).


        2018 was a year of awakening in terms of seeing the human role in huge environmental problems such as plastic pollution and climate change. It was the year of Greta Thunberg. It was the year the EU passed a ban (starting in 2021) on single-use plastics after the topic of ocean plastics had been on everybody’s lips the whole year. For those who thought speaking up about topics that worry us, changing our own habits or nudging our friends to do the same had little or no consequence in the face of global environmental threats, those examples can eradicate some of the doubt.

        If we keep building a strong movement for climate action during 2019, who knows what we can accomplish then?



        Climate events we will keep an eye on in 2019:

        • Agenda2030 Youth Climate Summit (Nuorten Ilmastokokous) in Helsinki, March 2
        • General election (also called “Ilmastovaalit” or climate elections) in Finland, April 14
        • UN Climate Summit “A race we can win, a race we must win” in New York, September 23
        • UN Climate Change Conference COP25 in Chile, November 11-22
