In the nine years since private equity and venture capital investments into sustainable technologies last crossed the $6 billion threshold, the problems caused by global carbon emissions have only intensified. Now, as the world confronts the reality that there’s not much time left to reverse course on carbon emissions and the impact they will have on life on earth, both corporate and private investors are once again stepping up their commitments to startups in the space. In 2018 global venture capital investment into startups focused on sustainability jumped 127% to $9.2 billion, the highest since 2010, according to a January report from Bloomberg New Energy Finance.
