Philanthropies are funding “tough tech” startups that are developing technologies to cut greenhouse gas emissions and mitigate the effects of climate change. Since 2014, the nonprofit Prime Coalition has channeled more than $24 million from wealthy donors and foundations to 10 ventures focused on that goal.
