Some of the investors are divesting from fossil-fuel related stocks and voting against directors who resist change.

The talks in Bonn may set out additional signals that governments are making an effort to clean up the environment.

Stansbury said he’d like to see wider adoption of carbon markets and a price of about $60 a ton by 2030 -- four times the current cost of emissions certificates in Europe. Higher carbon prices would help renewables at the expense of coal, oil and natural gas.

The envoys in Bonn will work on specific rules to apply the Paris deal, which would help give investors certainty which industries will prosper as governments tighten environmental protections.

Here’s how Paris will help investors make choices:

• It requires nations to set emissions targets and gradually tighten them.

• It asks countries to justify why their targets are adequate.

• It makes countries measure their emissions.

• It’s seeking to install rigorous standards to prove compliance with targets, including rules for countries wanting to collaborate or trade emission credits.

Maier said the priority for companies and governments is to back the UN’s overreaching goal of limiting temperature increases “to ensure that we stay within the 2 degrees, because that’s what ultimately what we want to see,” she said. Investors are pushing because they can’t diversify portfolios to deal with climate risks because those risks are attached to the whole economy.
