If the reduction of GHG (Greenhouse Gases) could be a public good, it ought to be provided mainly by the govt (or by NGOs), probably - however not essentially - along with industry. If cutting emissions is basically a commercial or non-public sensible, it is best left to plug forces (companies, exchanges) with science just providing steering and input to agents and players.

It would appear that environmental merchandise are public goods. Pure public merchandise are characterised by:
I. Nonrivalry - the price of extending the service or providing the great to another person is (close to) zero.

Most merchandise are rivalrous (scarce) - zero add games. Having been consumed, they're gone and don't seem to be accessible to others. Public goods, in distinction, are accessible to growing numbers of folks without any additional marginal cost. This wide dispersion of benefits renders them unsuitable for non-public entrepreneurship. It's impossible to recapture the total returns they engender. As Samuelson observed, they're extreme kinds of positive externalities (spillover effects).

II. Nonexcludability - it is impossible to exclude anyone from enjoying the benefits of a public smart, or from defraying its prices (positive and negative externalities). Neither can anyone willingly exclude himself from their remit.

III. Externalities - public goods impose prices or advantages on others - individuals or corporations - outside the marketplace and their effects are solely partially reflected in costs and also the market transactions. As Musgrave identified (1969), externalities are the opposite face of nonrivalry.
The standard examples for public product are lighthouses - famously questioned by one Nobel Prize winner, Ronald Coase, and defended by another, Paul Samuelson - national defense, the GPS navigation system, vaccination programs, dams, and public art (like park concerts). To the current we ought to add mitigating the consequences of climate change, cleaner air, and similar environmental goods.

It is evident that public merchandise don't seem to be necessarily provided or financed by public institutions. But governments frequently intervene to reverse market failures (i.e., when the markets fail to produce merchandise and services) or to reduce transaction costs so as to boost consumption or supply and, therefore, positive externalities. Governments, for instance, give preventive care - a non-profitable healthcare niche - and subsidize education as a result of they have an overall positive social effect.

Still, pure public product do not exist, with the doable exception of national defense. Samuelson himself recommended [Samuelson, P.A - Diagrammatic Exposition of a Theory of Public Expenditure - Review of Economics and Statistics, 37 (1955), 350-56]:

"... Several - though not all - of the realistic cases of presidency activity can be fruitfully analyzed as some quite a blend of those two extreme polar cases" (p. 350) - mixtures of personal and public goods. (Education, the courts, public defense, highway programs, police and fire protection have an) "element of variability in the profit that may go to 1 citizen at the expense of another citizen" (p. 356).

From Pickhardt, Michael's paper titled "Fifty Years when Samuelson's 'The Pure Theory of Public Expenditure': What Are We tend to Left With?":
"... It appears that rivalry and nonrivalry are presupposed to mirror this "component of variability" and hint at a continuum of goods that ranges from wholly rival to wholly nonrival ones. In explicit, Musgrave (1969, p. 126 and pp. 134-35) writes:

'The condition of non-rivalness in consumption (or, which is the identical, the existence of beneficial consumption externalities) means that the identical physical output (the fruits of the same issue input) is enjoyed by each A and B. This doesn't mean that the same subjective benefit must be derived, or maybe that exactly the identical product quality is offered to both. (...) Thanks to non-rivalness of consumption, individual demand curves are added vertically, instead of horizontally as in the case of personal product".

"The preceding discussion has proscribed the case of a pure social good, i.e. a smart the advantages of that are wholly non-rival. This approach has been subject to the criticism that this case will not exist, or, if in the least, applies to defence only; and in fact most merchandise which give rise to private benefits conjointly involve externalities in varying degrees and hence combine both social and non-public smart characteristics' ".

The Transformative Nature of Technology
It would appear that data - or, rather, technology - is a public sensible as it's nonrival, nonexcludable, and has positive externalities. The New Growth Theory (theory of endogenous technological modification) emphasizes these "natural" qualities of technology.

The applying of Intellectual Property Rights (IPR) alters the nature of technology from public to private sensible by introducing excludability, though not rivalry. Place a lot of simply, technology is "expensive to produce and low cost to reproduce". By imposing licensing demands on shoppers, it is made exclusive, though it still remains nonrivalrous (will be copied endlessly without being diminished).

Nevertheless, even encumbered by IPR, technology is transformative. It converts some public merchandise into private ones and vice versa.
Consider highways - hitherto quintessential public goods. The introduction of advanced "on the fly" identification and billing (toll) systems reduced transaction prices therefore dramatically that privately-owned and operated highways are currently common in several Western countries. This can be an example of a public sensible gradually going private.

Books reify the converse trend - from private to public goods. Print books - undoubtedly a non-public good - are now offered on-line free of charge for download. Online public domain books are a nonrivalrous, nonexcludable good with positive externalities - in alternative words, a pure public good.
Environmental product need an initial investment (the worth-exclusion principle demanded by Musgrave in 1959 does apply from time to time). Nor is strict nonrivalry doable - at least not simultaneously, as Musgrave observed (1959, 1969). Our world is finite - and thus is everything in it. The economic fundament of scarcity applies universally - and public goods are not exempt. This is often called "crowding" and amounts to the exclusion of potential beneficiaries (the theories of "jurisdictions" and "clubs" cope with this problem).
Nonrivalry and nonexcludability are ideals - not realities. They apply strictly only to the sunlight. As environmentalists keep warning us, even the air could be a scarce commodity. Technology gradually helps render several product and services - including, hopefully, environmental ones - asymptotically nonrivalrous and nonexcludable.
